The Reiss Tellurian is a very uniqkue, precise and very universal model of the earth, sun, moon and planets system . I'm aware of
only two other working instruments. It's build around 1965 in Liebenwerda Germany

Culpeper Type Microscope, signed Dollond c. 1800

Culpeper Type Microscope signed Dollond London c. 1800

in Mahogany Pyramidal Case.

This brass instrument stands on a box base with a concave mirror mounted on its centre. Three scrolled legs support the circular sttage and body. The stage has a keyhole slot and a pinhole
for accessories. The body consists of a draw tube that pushes into a cylinder fixed to the legs. The nose has an internal thread for objectives.

The tube has an eyecup, with a sliding dust cover, that screws over the eye lens, and a field lens. The nose has an internal thread for objectives. Trademark with Blunt logo. in the case. Lock but
no key.

Thomas Blunt (c1746–1822) apprenticed c1760 to Edward Nairne (1726–1806), and became his partner in 1774. Nairne introduced the Chest Microscope with the manufacture of a Cuff-style instrument
mounted on a tilting support attached to an elaborate mahogany box. Nairne continued to make instruments of this style at 22 Cornhill,Londonwell after Blunt joined the firm. Known Nairne instruments
were Cuff-style, thus given the Gould body and rotating objective system and the Blunt & Son trade card, it is possible that this particular instrument was created after Nairne died. 1793 Blunt
opened his own business up to 1802. His son become partner until 1822.

Engl. Compound Microscope c. 1800 not signed

Most Improved Type

This Microscope has a folding tripod base to which is attached a circular pillar surmounted by a compass joint. A short arm with rack and pinion adjustment, attached to the pillar
carries a limb with the stage. The stage has projections for forceps and spring clips. There is also a Martin superstage and a disc.

A condenser is also on the sleeve and has an adjustable angle arm.

The body tube has a 1-3/4 screw-inch screw in the conical nose, and screws to the arm. One screw –in eyepiece has three lenses, and there is a field lens. No drawtube.

Nuremberg Toy Microscope signed IM c.1800

Nuremberg Toy Microscope c.1800 signed IM

This three-pillared microscope was made in or around the town of Nuremberg, Germanyby the toy-makers of the area. These craftsmen were, and still are, famous for their wooden toys.
Nuremberg microscopes all are constructed with a main body consisting of two draw-tubes made of cardboard with lathe-turned wood trim. This microscope body is inserted into a third tube, which is
supported by three turned pillars on a wooden base. Focusing is achieved by sliding the microscope body inside the supportive cardboard tube. The sample remains fixed by a spring stage and is
illuminated from below by the substage mirror. In addition, the top tube (holding the eyepiece and field lenses) slides inside the base tube (which holds the objective lens). The optics consist
of only three lenses: the eyepiece, field, and objective lens. Samples were mounted in the wooden sample holder and held in place by the Bonanni spring stage. The illuminating mirror is
single-sided and mounted on a rotating wooden base. The microscope optical body is 15–18cm long, and the total height of this instrument is appx 32cm.

All Nuremberg microscopes have some degree of decoration. This microscope has shagreen covering the support base, and printed paper covering the body tube. This popular style, the
shagreen-covered, tripod design, was modeled after the more elegant microscopes by Culpeper of the early part of the 18th century. OtherNuremberg microscopes are characterized by having a
rectangular drum stand or a side pillar design.

Many of these instruments have initials burnt into the wood base, some surrounded by a circle, some by a heart shape.

This Cary/Gould-type brass compound microscope has a pillar with a rectangular cross section that screws into a socket on the wooden case lid. The body tube screws into an arm attached to
the top of the pillar. The tube has a cylindrical-shaped upper half and a conical-shaped lower half. The three objective lenses, each with a different magnification, can be used with the main
body as a compound microscope, or they can be screwed into the arm themselves for use as a low-power simple microscope. In either mode, they can be used separately, or screwed together for greater
magnification. The three lens eyepiece tube slides into the top of the body tube and can be partially withdrawn to increase magnification. It is focused with a rack and pinion that moves the stage up
and down on the pillar. The concave mirror is mounted on the pillar with a pin. The microscope disassembles to fit in its mahogany case and was designed to be small and portable for use in the
field.

Accessories: Bone slides, Life box, Magnifier, stage forceps etc.

Gould Type Microscope not signed

Cary Type Microscope not signed c. 1820

The microscope is a Cary -style brass compound microscope with cylindrical body tube and standard three-lens optics. The rectangular pillar, which mounts on hinge of its own wood box, has
a rack & pinion focus. There is no fine focus. The microscope body screws into a brass arm that press- fits into a rotating bracket at the top of the pillar (this allows the microscope to
rotate away from the case). The mirror has two reflecting sides, one plane and the other parabolic. The top case must be removed to use the microscope in transmitted light mode in order for the lamp
to be positioned correctly.

Binocular Microscope by Henry Crouch London No. 4376 c. 1870

This Binocular has an english foot. The binocular tubes have a transverse adjustment bar for coarse adjustment of the drawtubes. The nose has a thread for the
objective.. The curved limb has a rack and pinion coarse adjustment and the fine adjustment is a short lever screw in front of the tubes. The stage is squared.
